How many hours of sleep is good in a day? A few hours of sleep a day is best

It's usually 8 hours, as long as you don't feel tired during the day.

I seem to have seen it before, scientifically it is defined that a person's sleep time is 4 8 hours, and he can achieve full energy the next day, and he has a personal habit problem bin Laden sleeps 2 hours a day, which is also very good Hehe.

It mainly depends on your mental state during the day, if you sleep 6 hours a day, it is no problem to be full of energy during the day, and there are many people who sleep less.

Deep sleep for 5 hours is enough, note that I'm talking about deep sleep.

Most people sleep an average of seven to eight hours.

I've read some books. 8 hours is better. Try not to stay up late. Healthy sleep is good for your body.

Most people sleep an average of seven to eight hours, but that doesn't mean that sleep is necessarily seven or eight hours, and how much sleep you need each day varies greatly among your peers, and no single study can show exactly how many hours of sleep is the best time for you.

The amount of time it takes to get you to a state of energy the next day is the amount of sleep you need. There are many examples in the world that show that it is possible to sleep three to four hours a day, such as Edison, Napoleon, Margaret Thatcher, etc., these people are called short sleepers; There are also people who sleep nine to eleven hours a day, such as Albert Einstein and other people called long sleepers, and these two are not a large proportion of the population, accounting for only 1% to 3% of the population.

Many people are too busy with work and study, and gradually exercise to reduce their sleep time from the age of 16 to 18, so as to devote more time to work and study, and they sleep about six to six and a half hours a day, but feel that the day has become pleasant and fulfilling. Compared to people who sleep long, they fall asleep faster, wake up less often during the night, and dream less often.

Some people have observed and analyzed the personalities of the two, and found that people who sleep less generally have a more stable, optimistic, and active personality, and are rarely indecisive and hesitant when encountering problems, and are energetic and work efficiently. Among these people, there are people who are in a relatively stable psychological state, some people who have obsessive-compulsive habits, and some people who are willing to live too busy lives. This kind of person deals with difficulties in the following ways:

As long as possible, don't think about those troublesome things" and have confidence in life and career.

People who sleep for a long time do not have a particularly obvious tendency, and most of them show seriousness, pursuit of perfection, and good thinking. Some are depressed, timid, and often cause dissatisfaction. They have a high evaluation of the value of sleep, believing that sleep is too important for physical health, and they can't be slack, and a little lack of sleep is very easy to cause anxiety.

In short, the amount of sleep depends on personal needs, if you feel low energy, you should make appropriate supplemental sleep, good sleep is the basis for determining your full creativity. Excessive sleep is not quite commensurate with the rhythm of modern society and can be changed slowly.

The total sleep time per day and night in a person's life decreases with age, and after the age of seventy-five, deep sleep almost completely disappears, so it is easy to wake up, the number of awakenings increases, and the number of wake-ups is more than when they are young, so the energy and physical strength of the elderly during the day will not be as good as when they were young. Some elderly people have more opportunities to sit at home and nap during the day, and the lunch break is longer, which will affect the sleep time at night. If the elderly like to go out, they still sleep soundly at night and can sleep until dawn.

According to the person's physiology and brain recovery time, as long as you can ensure two hours of deep sleep every day, of course, you have to deduct the pre-sleep time and light sleep time, for example, even if I lie down and do nothing, it will take an hour and a half to feel sleepy, plus half an hour of light sleep before I really go into deep sleep, so I only sleep 4 hours a day, and Einstein also sleeps 4 hours a day. Of course, it varies from person to person, some people lie down for three or four hours before falling asleep, I used to be in this situation, lying down to think about all kinds of scientific problems, sometimes I came to inspiration more and more energetic until dawn did not fall asleep, and even sat up to think, and then forced myself not to think about the problem, only to shorten the pre-sleep time to hours, but I don't want to be too bored and can't fall asleep, you can put on some emotional audio radio to listen, don't listen to the content, easy to fantasize, just as hypnosis.

Many people have the misconception that you should sleep 8 hours a day. In fact, getting 7 hours of sleep a day can keep you in the best possible shape. Sleep experts have specifically counted and demonstrated that people who sleep 7 times a day and disappear live the longest.

In fact, 7 hours of sleep is better than 8 hours, 6 hours is better than 9 hours, ......and so on

Many times we sleep a lot not because it is good for our body, but because we make ourselves feel good, which is like eating enough to make ourselves feel good, but in fact it is not good for our body.

From a young age, we were told to get enough sleep every day. How many hours a day does it take to get enough sleep?

Personally, I think it's best to get a full 6 hours of sleep, and I will feel good when I wake up. If you sleep for more than 12 hours, you will feel pain all over your body.

The above is purely personal experience.

When it comes to sleep, it's not that sleeping for a long time is good for you. It's about what effect you want. In general, it is best to fall asleep at 11 p.m., and there is a saying that this is:

If you don't sleep at 12 o'clock, you are shameless (referring to beauty), and if you don't sleep at 3 or 4 o'clock, you will be dead. There are two shifts at work, in fact, sleeping is the same, if the conditions allow, 11-13 o'clock at noon is the most active time for the heart I mind if you sleep for an hour or half an hour, and you will not be tired after working overtime at night. The average sleep time at night is half past 10 or 11 to 5 in the morning

30 to 7 o'clock.

It's fine to admit that 8 hours is fine, but you have to make sure that you get a good night's sleep.

Normal adults, eight hours. It is best for the recovery of the body and the maintenance of energy for the day. 15-18 years old, eight and a half hours; 6-15 years old, nine hours; 4-6 years old, nine and a half hours; years, ten hours; 1. More than 10 hours for children under 5 years of age, and even 13 hours for babies under 4 months.

If you are an adult, it is better to sleep for at least eight hours.

7 hours of quality sleep is enough.

7-8 hours of sleep for 18-59 years old, and hours of sleep for 60-70 years.

Assuming age x, the optimal sleep time y approximately satisfies y=21-6x. However, some experts have suggested that the elderly need longer sleep than adults due to their weak qi and blood, so they have y=22-7x.

Sleep time refers to a natural physiological phenomenon of humans and animals, consciousness is natural, usually regular temporary suspension, during which the process time of physical recovery can reach the time of closing the eyes and resting, and the cerebral cortex is in a state of rest.

Sleep time can be divided into intermittent sleep and continuous sleep, and the sleep time referred to in general life refers to the total sleep time in a day, that is, the sum of all the time in the sleep state.

From the perspective of traditional Chinese medicine, a person only needs to sleep for three hours a day. But it's about deep sleep. So be sure to go to bed around half past ten, not too early, not too late, and wake up naturally in the morning. Have a biological clock. Such a lifetime is long enough and very healthy.
